Question

Which of the following is a condition that must be met for a population or an allele to be in Hardy-Weinberg equilibrium?

A The population in question must be small
B Organisms must be free to migrate into or out of the population
C New mutations must be introduced to the gene pool at a consistent and unfluctuating rate
D Organisms in the population must express no mating preferences

Answer 1

The answer is D) Organisms in the population must express no mating preferences.

Some of the conditions that must be met for a population or an allele to be in Hardy-Weinberg equilibrium are:

1. The population must be very large - so A) could not be the right answer.
2. There must be no migration and population must be isolated - so B) could not be the right answer.
3. There must be no mutations - so C) could not be the right answer.
4. There must be random mating, which means there are no mating preferences - so, D) is the right answer.
